How is the proportion of hydrogen to helium in the Sun's core changing over time?

Biology
1 answer:
harina [27]3 years ago
7 0

Answer: The percentage of the helium will increase with the decrease in the percentage of the hydrogen.

Explanation:

The conversion of the hydrogen into helium occurs by the nuclear fusion of the hydrogen atoms. This process reduces the hydrogen density and reduces the energy production inside the core region. Typically, in the core region of the hydrogen is converted into the helium by nuclear fusion. Four hydrogen atoms are collectively fuse to form one atom of helium. This process involves the production of heat energy.

Alzheimer's disease is a form of dementia that causes problems with memory. Alzheimer's accounts of 60-80 % of dementia cases and interferes with normal life. It is not a normal part of aging, even though people think that old people are forgetful. Alzheimer's usually starts with difficulty remembering newly learned information. Memory loss is not necessarily Alzheimer's.

5. List three mechanisms by which Earth's albedo can be increased.
KIM [24]

Explanation:

1. A decrease in the number of greenhouse gases that humans produce will result in lowered global temperatures. This will allow the ice sheets in the polar regions to increase increasing also albedo.

2. Using light-colored building materials on houses and pavement in urban centers will work towards increasing albedo as more sunlight is refelcted back by built environments.

3. Decreased deforestation/increase in aforestation increases the earth’s sirface albedo because vegetation reflects back more sunlight than the earth’s bare surface.

Sonja [21]

1. taxonomic category within a kingdom-phylum

This taxonomic category is at level below Kingdom and above Class (e.g Arthropoda, Chordata, Mollusca)

2. plant that lives on decaying organic matter-saprophyte  

Saprotrophic plants or saprophytes use saprotrophic nutrition meaning that have extracellular digestion to process death organic matter.

3. break down of complex molecules into simpler ones- fermentation  

Fermentation is a metabolic process that breaks down organic substrates in order to obtain energy. These processes are performed without the presence of oxygen (anaerobic processes).

4. multi-nucleated thread-like structures of fungi hyphae

This is one of the basic structural unit of fungi-long, filamentous structure that can form network-micelium. It is used for vegetative reproduction.

5. mycelia responsible for obtaining food from non-living organic material rhizoids

Rhizodis are unicellular or multicellular stuctures (branching hyphae) found in fungi that are similar to root hairs of plants. These structures are involved in saprotrophic nutrition of fungi.

6. asexual reproduction of yeast budding  

Budding is a type of asexual reproduction in which a new organism develops from some generative anatomical part of the parent organism.

7. a group of hyphae mycelia

Mycelum is fungi’s vegetative body that consists of network of branching hyphae.

8. reproductive cells which can tolerate bad conditions spores

Spores are reproductive structure, part of the fungi life cycle, that can be involved in sexual or asexual reproduction, vary in structure that are formed in. Spores are usually haploid and unicellular.

9. structures which house the reproductive formation fruiting

Fruit is a structure in flowering plants that contains seed and it is responsible for seed dispersal and nutrition.

10. mutually positive relationship between two species symbiosis  

Symbiosis is biological interaction between two species that can be mutualistic, commensalistic, or parasitic. More specifically, symbiosis refers to positive interaction for both members of it.

11. plant or animal which supports a parasite host

Parasitic relationship between species is the one in which organism (the parasite), lives on or in another organism (host).This relationship is positive for parasite but negative for the host.
